The World Wide Web technology was developed in the early nineties. Since then it has had a great impact on society, and its use has expanded beyond the research communities where it was first adopted. The theme for this ...

A common requirement in distributed multimedia systems is the ability to transmit continuous media streams of various kinds between producing and consuming endpoints. It is important that support for continuous media ...

Oljeselskapene vurderer å plassere oljeproduksjonsanlegg på havbunnen som skal styres fra land, 200 km unna, ved hjelp av fiberoptiske kabler. Målet med oppgaven har vært å finne en sanntids kommunikasjonsløsning som ...

Main characteristics of GEO-stationary satellites are long delay, high bit error rate and large asymmetry. TCP handles these characteristics poorly and dows not utlilize a satellite link well. TCP acceleration is a solution ...

The main characteristics of the satellite channel are large delay and bit error. Both characteristics make TCP perform poorly in satellite communication, and force optimization of TCP and even definition of new transport ...

The main topics in this thesis are information and communication technology(ICT; used interchangeably with IT) and development, and health information systems development in South Africa. The thesis is based on field work ...

The RenderMan Interface is interesting in the context of scientific visualization. With the RenderMan shading language, programmable control over the steps in the rendering pipeline is possible. As an example of this, a ...

This thesis addresses the implementation and use of media spaces. The work leading to this thesis consists of a field experiment and the evalua-tion of this and other similar experiments. The project was named the Virtual ...

Generic types in Java. This report discusses the lack of generic types in the programming language Java, which is nice to have when writing fast, generic methods that can be used in different contexts. It is possible to ...

Network connectivity is no longer an expensive add-on. It has become a basic feature of almost any computing facility, gradually it will be found in products offered in parts of the consumer electronics market traditionally ...

This paper is concerned with the protocol engine in the SWIPP (Switched interconnection of parallel processors) project. In particular the network protocols and the network interface are studied. A proposal for new protocols ...

Thesis is based on three different aspects of Kalman filtering. >Kalman filters for navigation. Investigate the difference between a Extended Kalman Filter and a Linearized Kalman Filter with feedback. And show how ...

There is a broad consensus in the database research community that the traditional ACID properties are not suitable for certain application domains. Especially, long-lasting and information sharing transactions are not ...

The focus of the work of this Cand. scient. thesis has been placed upon understanding and developing a concept for using digital communication in safety-critical applications. It is increasingly common to use programmable ...

Ionic consentrasions causes electric impulses in the heart. To describe the hearts activity, this thesis will consentrate about two simple models: Hodgkin-Huxley and the monodomain model. These models contain a lot of ...

Design av mobile systemer har gitt systemutviklere nye problemstillinger som man ikke før har møtt. Innenfor CSCW har to teoretiske retninger hver sin tilnærming til hvordan slik design bør foregå : Cognitive science ...

One of the most important features of database systems is transaction management. Transaction management ensures concurrency- and recovery control. In conventional database systems, classical transaction management ensures ...

Dette er en hovedfagsoppgave innenfor fagområdet kommunikasjonssystemer ved Institutt for Informatikk ved Universitetet i Oslo. Multimediaservere behandler store, komplekse, kontinuerlige og tidsavhengige dataelementer ...

Distributed multimedia applications have Quality of Service (QoS) requirements that current communication systems are not able to handle. Dynamic Configuration of Protocols (Da CaPo) is a framework for dynamically ...

This thesis describes how the use of more than one type of programming languages can be useful in high-performance computing. Scripting languages like Python and Perl are used for control and computational steering, while ...

Usenet is the name of a world wide network of servers for group communication between people. From 1979 and onwards, it has seen a near exponential growth in the amount of data transported, which has been a strain ...

In this thesis, signal processing is performed on the output from the pulsed laser photoacoustic instrument monitoring crude oil in water. The instrument is constructed to perform inline monitoring of produced water in the ...

Sammendrag: My focus in the masters thesis lies mainly on two aspects: The representation of problems in learning environments as sources of internalization. I also focus on how ICT can help learners cope with the semiotic ...

Turnusplanleggingsprosessen innebærer å tilordne ulike vakttyper til personer under gitte betingelser. Et aktuelt spørsmål er om dataverktøy kan erstatte den manuelle utarbeidelsen av turnusplaner. Et slikt verktøy må være ...

Eksisterende verktøy for turnusgenerering har vist seg å ha begrensede muligheter til å tilpasse turnusplanene etter behov. For å oppnå en maksimal effektivitetsøkning ved overgangen fra manuelle prosedyrer for ...

Mobile informatics is the subject of my research, where both empirical and theoretical studies are prominent. The empirical work consists of case studies I have accomplished in two different Norwegian companies. The first ...

This study experiments with novel ways to design biorthogonal wavelet filters for use in signal/image compression applications. The filters are constructed by directly minimizing the energy of a decomposed signal- or image's ...

Oppgaven ser på noen aspekter rundt QoS i dagens og neste generasjons Internett. Dette emne debatteres mye i IETF og andre organisasjoner. For å innføre differensierte tjenester i Internett, må det legges inn ny funksjonalitet ...
